Rock Skipping

Today we were highlighted on the BYU homepage with a video made by BYU broadcasting about rock skipping.  The video highlights two methods of skipping stones and our recent work with the Waboba-water bouncing ball. The Daily Herald joined us while we were filming at Utah Lake in May. The article by James Roh gives a [...]

Bouncing in Puddles

When a ball is dropped into a puddle, momentum is exchanged between the impacting ball and the surrounding fluid, decreasing the rebound height. At impact, a radial jet and splash curtain are formed as fluid is instantaneously displaced by the falling ball. During rebound, the splash curtain is drawn in and a column of fluid [...]

Buoyant Rising Spheres

When a buoyant rising sphere exits the free surface there are several angles of trajectory and heights observed. Children experience this when playing with a ball while swimming. The pop up height and direction of trajectory above the free surface are dependent on the release depth of the sphere below the free surface. The release [...]

Time Warp – Again

I was very excited to visit the set of Time Warp last April and talk about the work I did as a PhD student.  I haven’t posted the event until now because I thought it would be better to post a clip from the show.  I tried to get the producer to send me free [...]

Axisymmetric Projectiles

Previous studies have shown that applying a hydrophobic coating to one-half of a hydrophilic sphere will cause asymmetric cavity formation and a deflection in the trajectory of a sphere.  Half of an axisymmetric projectile will be coated with the hydrophobic coating and dropped in a similar manner to determine if there is similar asymmetric cavity [...]

Bubble Rupture

           When the conditions are right, a solid sphere can pass through a soap bubble without rupturing the soap film. As the sphere passes through the soap film, a pinch-off occurs and the soap film reseals itself. Predicting whether or not a soap film will rupture is dependent upon the speed [...]
